Percentages of mass loss and steps of thermal decomposition of the LEO, β-cyclodextrin (β-CD), physical mixture (PM), and LEO/β-CD (CE) complex.
| Mass loss % | ||||
|---|---|---|---|---|
| 1st stage | 2nd stage | 3rd stage | 4th stage | |
| LEO | 93.94# | — | — | — |
| β-CD | 12.51∗ | — | 72.88∗∗ | 10.76∗∗∗ |
